Test 400 has recently exploded onto the market and is very popular among many bodybuilders of all ages.

Be warned this is a very strong blend of Testosterone.

Zyroxx Test 400 – Side Effects

Test 400 can cause side effects such as acne, hair loss, prostate enlargement and it will shut down your natural hormone function. Most of the side effects begin as the body turns high levels of testosterone into estrogen due to the aromatase enzyme.

This side effect can be controlled by the use of anti-estrogens such as Nolvadex, Proviron or Arimidex which all work in different ways in controlling the estrogen but still get the job done. Anti estrogen products will help keep any water retention down so you do not look as bloated or puffy and will also combat any gyno (bitch tit) problems that some users are sensitive to.

Test 400 is a seriously strong blend of testosterones which in some users can convert to dihydrotestosterone which is a worry for some as this can cause male pattern baldness but again this can be controlled by use of Finasteride and Regain.

Zyroxx Test 400 – Benefits in Bodybuilding

As with any testosterone it will increase nitrogen retention in the muscle, there are reports of it increasing IGF-1 in the muscle tissue and liver and it also has an active role in repairing exercised damaged muscle tissue through satellite cell activity.

Test 400 is very highly anabolic and very highly androgenic and will cause a massive increase in strength and size which you will physically see in approximately 14 days. Test 400 is very popular amongst bodybuilders today and I have physically seen it produce dramatic results for competitive bodybuilders who are preparing for shows in 2012.

Zyroxx Test 400 – Stacking

Test 400 is the ultimate testosterone mass builder and is usually stacked on a bulking phase with the likes of Deca Durabolin and Dianbol or Anadrol . The Dianabol or Anadrol 50 should be used in the first 4-6 weeks of the cycle to kick start the whole process by up regulating the receptor sites, the Test 400 and Deca Durabolin would be continued for the full 8-12 weeks.

Towards the end of such a course many bodybuilders would add hardening steroids to stay in an anabolic state and tighten the gains made. To ensure you keep most of your gains when you come off a cycle including Test 400 it is very important that post cycle therapy products are used such as Nolvadex, Clomid and HCG.
